When the Alliance to Restore the Republic learned that the Death Star I was located at Despayre, they sent two CR90 corvettes from Ethar group to investigate. They arrived to find that the Death Star had already left, having destroyed the planet first. Furthermore, Imperial forces had anticipated the Rebel's arrival and lingered there to set a trap. The corvettes were disabled and the Imperials dispatched repair crews aboard Ceptor 1 and 2 to board and capture the corvettes, under the protection of Assault Gunboats.

They managed to finish their repair operations and escape into hyperspace just after Rebel forces arrived to disable the corvettes and recapture them.
